In simple words: This code describes a baby born smaller than expected for their age, but their length is relatively normal. This might mean there was a problem with their growth and nutrition before birth.

This code classifies newborns whose weight is below the 10th percentile for their gestational age, but whose length is above the 10th percentile.This indicates that the infant is lighter than expected given their gestational age, but their length is relatively proportionate. This condition suggests a possible issue with fetal growth and nutrition during pregnancy.Further investigation may be needed to determine the underlying cause.

Example 1: A 37-week-gestation newborn weighing 2,000 grams (4.4 lbs) with a length of 50 cm (19.7 inches). The weight is below the 10th percentile, while the length is above the 10th percentile., A newborn delivered at 39 weeks gestation who presents with a birth weight below the 10th percentile for gestational age, indicating intrauterine growth restriction (IUGR). Despite the low weight, the infant's length falls within the normal range for gestational age., A mother with pre-eclampsia delivers a newborn at 36 weeks gestation. The newborn’s weight is below the 10th percentile but the length is above the 10th percentile. The infant requires close monitoring for potential complications associated with IUGR.

Maternal history (including prenatal care, weight gain, presence of any complications like preeclampsia or gestational diabetes), gestational age, birth weight, length, head circumference, Apgar scores at 1 and 5 minutes, any immediate postnatal complications.

** Further investigations may include assessment of placental function, fetal blood flow studies, and genetic testing to determine the underlying cause of the disproportionate growth.
